Product Description
The Kerns Technology Fiber-mixed Design 980/1550 Fused Taper Wavelength Division Multiplexer (SWDM) is a high-performance passive optical component engineered for Erbium-Doped Fiber Amplifier (EDFA) and fiber laser systems. It adopts a dual-fiber configuration (Corning HI1060FLEX for public/pump ports + Corning SMF-28e for signal ports) to optimize compatibility with 980nm pump light and 1550nm signal light.
Leveraging advanced fused taper technology, this SWDM achieves ultra-low insertion loss (≤0.3dB), high isolation (≥20dB), and minimal polarization-dependent loss (≤0.1dB) across 980/1550±10nm bands. Its flexible package options (e.g., φ3.0×154mm for bare fiber, 90×20×9.5mm for loose tube) and wide temperature range (-40~+85°C) ensure reliable integration into both laboratory and industrial optical setups.
Product Features
1. Fiber-mixed Optimization
Combines Corning HI1060FLEX (low-loss for 980nm pump light) and SMF-28e (standard for 1550nm signal light) to maximize power efficiency in EDFA systems—outperforming single-fiber WDMs in pump-signal compatibility.
2. Ultra-Low Loss & High Isolation
Insertion loss ≤0.3dB (minimizes signal/pump power attenuation)
Isolation ≥20dB (prevents 980nm/1550nm cross-talk, protecting laser sources)
3. Robust Performance Stability
4. Flexible Customization
Multiple package dimensions (φ3.0×154mm, 90×20×9.5mm, etc.) for space-constrained setups
Pigtail options: 250μm bare fiber, 900μm/2mm/3mm loose tube
Fiber lengths: 0.5m~3m (customizable)
Product Applications
This fiber-mixed 980/1550 SWDM is specifically designed for:
Fiber EDFAs: Combines 980nm pump light with 1550nm signal light to enhance amplification gain and efficiency.
Fiber Lasers: Separates 980nm pump wavelengths from 1550nm laser output to stabilize laser performance.
Optical Test Systems: Serves as a precise wavelength combiner/separator in EDFA characterization setups.

FAQs
Q1: How does the fiber-mixed design benefit my system?
A1: The dual-fiber configuration (HI1060FLEX + SMF-28e) optimizes loss performance for both 980nm pump light and 1550nm signal light—unlike single-fiber WDMs, which may compromise efficiency for one wavelength.
Q2: What’s the impact of adding connectors?
A2: With connectors, insertion loss increases by 0.3dB and return loss decreases by 5dB. We recommend factory-installed connectors (aligned to fiber specifications) for optimal performance.
Q3: Can I customize the package size for my equipment?
A3: Yes. We offer multiple standard package dimensions (e.g., φ3.0×154mm, 90×20×9.5mm) and can provide custom sizes to match your system’s installation space.
Q4: Is this SWDM compatible with high-power pump lasers?
A4: It supports typical 980nm pump power levels (≤2W) used in most EDFAs; for higher-power requirements, we can provide customized high-power versions.
